EVALUATION OF VOCAL CORDS MOTIUTY BY HIGH FREQUENCY US (HFUS) IN PATIENTS WITH LARYNGRAL CARCINOMA SUBMITED TOCONSERVATIVE TREATMENT. w, Robirosa A*, Nuiiez 1,Vilana R, Gilabert R, Nicolau C, Bru C Ultrasound and Radiotherapy*Departments. Hospital Clinic. University of Barcelona. SPAIN. Few methods are available for the evaluation of vocal cords function and most of them are invasive or unconfortable. The aim of this study was to assess the usefulness of HFUS to evaluate the motility of vocal cords. PATIENTS: 23 patients with local laryngeal carcinoma conservatively treated (radiotherapy), as well as 10 normal subjets, were shdied =HODs: The study was perfomwd by hlgh frequency ultrasound (8 Mhz Tosblba SSH-140 A) duting fonation Vocal cords visualization. presence (“i”) and videorenistered. and amplitude of-vocal cords movements were as&ed , and the result.5 classifkd as non vlsualizatlon. minimal, medium and normal osclIation. Results were compared with the control group aad the result of vldeostromboscopy and voice analysis in the group of patients. RESULTS:In 9 of 23 patlents (399b) the visualization of vocal cords was Impossible, because the calclflcatlon of thyroidal cartilages, being well visualized ln normal sub@%. USHF allowed to identify patients with paralysis or depressed motility. CONCLUSION: HFUS of the vocal cord when possible, is a easy and reliable method to study motility in patients with laringeal neoplasm:.
